Clean water became a very important requirement. A wide range of tools and technologies created in order to obtain clean water easy. But as a technology, need an understanding of how to use and manage.

Clean water became a very important requirement. A wide range of tools and technologies created in order to obtain clean water easy. But as a technology, need an understanding of how to use and manage.

Norma Alcantar, a scientist from the University of South Florida USA, looking not pull water purification technology that exists today, especially for people in developing countries, because not everyone is able and willing to learn and perform both cases, the result is a tool and these technologies are ignored and not used at all. Not to mention the maintenance costs to be incurred in order to keep it functioning optimally water purification equipment and technology today.

Once again, nature and history have given an example. Together with some colleagues decided to examine a plant capable of living on barren land and are often found around the world. The choice fell on a prickly pear cactus or Latin language Opuntia ficus-indica. Cactus species have been used since the 19th century by the people of Mexico as a water purifier.

Alcantar found that the viscous sap found in plants and usually serves as a store of water turned out to be thickening. In the trials with the addition of water and mixed with sediment and bacteria at high levels, there was a clumping of particles settle to the bottom sediments and water. The sap has also resulted in 98% of bacteria together and make it easier to filter.

Communities in developing countries can heat a piece of cactus in order to remove the sap, then add it to water that needs purification, added Alcantar. The prevalence of cactus, affordability and culture made of natural materials such as water purification technology is interesting. Research results have also been published in the journal Environmental Science and Technology.

Although it looks simple, there seems to be done so that the nature of technology to function optimally. This was revealed by Colin Hirwitz, head of technology at the company GreenOx Catalysts catalyst, which underlines there are still some issues that need to be answered, including how much land and water needed to grow a cactus for water purification purposes in greater numbers, and how one knowing that all the bacteria that fused is removed from the purified water is a natural technology.

However natural alternative technologies remains attractive, and only needed a few more steps to achieve optimal results. Availability and ease in making the process of appropriate technology.
